Description

Technical Field

[0001] The utility model relates to the field of safety monitoring of the foundation of an offshore wind power generator, and particularly relates to a mounting bracket for a fixing stud of a waterproof box of an offshore wind turbine acquisition device. Background Art

[0002] In the field of safety monitoring of the foundation of an offshore wind power generator, an acquisition device is required to collect and transmit data at a monitoring point for a long time. The acquisition device is usually arranged outside the offshore wind power generator. Therefore, it is necessary to cover the acquisition device with a waterproof box to prevent the acquisition device from being damaged due to long-term exposure.

[0003] During actual installation, usually in a wind turbine foundation prefabrication factory, the fixing studs of the waterproof box are pre-welded and fixed on the outer periphery of the foundation of the offshore wind power generator. Threaded inner holes are provided in the fixing studs. After the wind turbine is hoisted later, fixing bolts adapted to the threaded inner holes of the fixing studs are used to fix the waterproof box of the acquisition device on the foundation of the power generator. When actually welding the fixing studs, usually, points are marked and positioned according to the positions of the fixing bolt holes for installing the waterproof box designed. Then, the worker holds the fixing stud and performs full welding and fixing at the positioning point. However, this welding method has the following disadvantages:

[0004] A single waterproof box is usually fixedly connected to the foundation of the power generator by using four fixing bolts. Therefore, it is necessary to pre-position the positions of four fixing studs on the foundation of the power generator, and then the fixing studs are welded and fixed separately at each point. Stress will be generated during the process of welding and fixing the fixing studs, which will cause slight deformation and displacement of the fixing studs. At the same time, since the four fixing studs are welded separately and there is no correlation between them, during actual welding, the four studs will all undergo deformation displacements with inconsistent sizes and directions. The inconsistent deformation displacements will cause the mutual distances between the four welded studs to not match the positions of the fixing bolt holes for installing the waterproof box designed. Generally, in an ideal state, when actually installing the waterproof box, due to the above-mentioned deformation displacements, the waterproof box can barely fix three fixing bolts at the corresponding fixing stud positions, and sometimes even only one or two fixing bolts can be installed, greatly reducing the stability and safety of the waterproof box.

[0005] Therefore, how to ensure that the welding position of the fixing stud is at its designed position to ensure the reliability of the waterproof box installation is a technical problem that needs to be solved urgently by those skilled in the art. Content of the Utility Model

[0006] The technical problem to be solved by the present utility model is to provide a mounting bracket for the fixing studs of the waterproof box of an offshore wind turbine acquisition device. The fixing rod can fix the positions of the fixing studs during welding, avoiding deformation and displacement of the fixing studs during welding, ensuring that each fixing stud can be welded and fixed at the designed position. When installing the waterproof box, the fixing bolts can be threadedly connected to the corresponding fixing studs, ensuring the stability and safety of the waterproof box.

[0007] In view of the above technical problem, the technical solution provided by the present utility model is a mounting bracket for the fixing studs of the waterproof box of an offshore wind turbine acquisition device, including a fixing frame. A plurality of fixing positions are provided on the fixing frame, and a fixing rod perpendicular to the fixing frame is provided at each fixing position. The end of the fixing rod facing away from the fixing frame is a fixing end. The number and positions of the plurality of fixing ends are used to correspond to the number and positions of the fixing studs, and the fixing end is used to fix the fixing studs.

[0008] Further, a threaded through hole is provided in the fixing position, and the aperture of the threaded through hole is adapted to the threaded inner hole of the fixing stud. The fixing rod is a fixing screw rod screwed in the threaded through hole, and the fixing end is used to be screwed in the threaded inner hole of the fixing stud to fix the fixing stud.

[0009] Further, the forward distance between the fixing end and the fixing frame is less than the depth of the threaded inner hole of the fixing stud.

[0010] Further, the forward distance is equal to four-fifths of the depth of the threaded inner hole of the fixing stud.

[0011] Further, a handle is provided at one end of the fixing screw rod facing away from its fixing end.

[0012] Further, the number of the fixing positions is four, and the connection line of the four fixing positions is rectangular.

[0013] Further, the fixing frame is an I-shaped frame, and the I-shaped frame includes two parallel cross beams and a longitudinal beam connecting the two cross beams. Two fixing positions are provided on each cross beam.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) A fixing rod perpendicular to the fixing frame is provided on the fixing frame. The fixing rod can fix the positions of the fixing studs during welding, avoiding deformation and displacement of the fixing studs during welding, ensuring that each fixing stud can be welded and fixed at the designed position. When installing the waterproof box, the fixing bolts can be threadedly connected to the corresponding fixing studs, ensuring the stability and safety of the waterproof box.

[0016] (2) Threaded through holes are provided at the fixed positions. The fixing rods are fixing screws, and the fixed ends can be screwed into the threaded inner holes of the fixing studs. In this way, the fixing rods can fix the fixing studs by means of threaded connection. At the same time, it is convenient to separate the fixing rods from the fixing studs after welding is completed. Moreover, the fixing rods are threadedly connected to the threaded through holes, and the distance between the fixed ends and the fixing brackets can be adjusted to adapt to fixing studs with different depth dimensions.

[0017] (3) The front extension distance is less than the depth of the threaded inner hole of the fixing stud. During actual use, the opposite ends of the fixing stud and the fixing bracket can be fitted together.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application: Specific Embodiment 1:

[0024] Refer to Figure 1 , a mounting bracket for a fixing stud of a waterproof box of an offshore wind turbine collection device of the present utility model (hereinafter referred to as the mounting bracket) includes a fixing bracket 1. Multiple fixed positions are provided on the fixing bracket 1. Fixing rods perpendicular to the fixing bracket 1 are provided at each fixed position. The end of the fixing rod facing away from the fixing bracket 1 is the fixed end 21. The number and positions of the multiple fixed ends 21 are used to correspond to the number and positions of the fixing studs. The fixed end 21 is used to fix the fixing stud 4. With such a setting, by using the fixing rods and the fixing bracket 1, the positions of the fixing studs 4 can be fixed during welding, avoiding deformation and displacement of the fixing studs 4 during welding, ensuring that all the fixing studs 4 can be welded and fixed at the designed positions. When the waterproof box is installed, the fixing bolts can be threadedly connected into the corresponding fixing studs 4 to ensure the stability and safety of the waterproof box.

[0025] Specifically, in this embodiment, a threaded through hole 3 is provided at the fixed position. The aperture of the threaded through hole 3 is adapted to the threaded inner hole 41 of the fixing stud 4. The fixing rod is a fixing screw 2 screwed into the threaded through hole 3. Then, the external thread of the fixing screw 2 is adapted to the internal thread of the fixing stud 4. The end of the fixing screw 2 facing the fixing stud 4 is the fixed end 21. The fixed end 21 has an external thread adapted to the threaded inner hole 41 of the fixing stud 4. The fixed end 21 is used to be screwed into the threaded inner hole 41 of the fixing stud 4. In this way, the fixing stud 4 can be fixed by means of threaded connection. At the same time, it is convenient to separate the fixing rod from the fixing stud 4 after welding. Moreover, the fixing rod is threadedly connected to the threaded through hole 3, and the distance between the fixed end 21 and the fixing bracket 1 can be adjusted to adapt to fixing studs 4 with different depth dimensions.

[0026] Of course, in other embodiments, the fixing rod can be a smooth rod. At this time, a fixing clip such as a three-jaw chuck is provided on the fixed end 21. During actual use, the fixing stud 4 is clamped by closing the fixing clip to fix the fixing stud 4. After welding, the fixing clip is opened to release the fixing stud 4, realizing detachable fixation.

[0027] In this embodiment, as Figure 1 shown, the front-out distance between the fixed end 21 and the fixing bracket 1 is less than the depth of the threaded inner hole 41 of the fixing stud 4. In this way, during actual use, by screwing the fixing stud 4 onto the fixing screw 2, the opposite ends of the fixing stud 4 and the fixing bracket 1 can be brought into contact with each other. Furthermore, the fixing stud 4 is positioned by the fixing bracket 1 to ensure that the four fixing studs 4 are coplanar. During welding, the four fixing studs 4 can be simultaneously attached to the peripheral surface of the power generation fan foundation to ensure the accurate installation position of the fixing studs 4. Specifically, the front-out distance is equal to four-fifths of the depth of the threaded inner hole 41 of the fixing stud 4. In this way, the fixing screw 2 can provide stable and reliable support for the fixing stud 4, avoiding the fixing stud 4 from falling off or shifting due to vibration during welding.

[0028] Of course, in other embodiments, when the actual requirements are met, the front-out distance can be equal to one-third or two-thirds of the depth of the threaded inner hole 41 of the fixing stud 4. Or in other embodiments, the front-out distance can be greater than the depth of the threaded inner hole 41 of the fixing stud 4. At this time, it is necessary to ensure that after each fixing stud 4 is screwed onto the corresponding fixing screw 2, the distances between the fixing studs 4 and the fixing bracket 1 are the same, ensuring that the ends of the fixing studs 4 facing away from the fixing bracket 1 are coplanar.

[0029] In this embodiment, as Figure 1As shown in the figure, a handle 5 is provided at one end of the fixing screw 2 facing away from the fixed end 21. The handle 5 can be used to facilitate screwing the fixing screw 2 in and out of the threaded through hole 3. Of course, in other embodiments, when the actual requirements are met, the handle 5 may not be provided. In this case, a hexagonal prism may be provided at one end of the fixing screw 2 facing away from the fixed end 21, and the fixing screw 2 can be driven to rotate by an electric wrench adapted to the hexagonal prism, or the fixing screw 2 can be rotated only by manual screwing by an operator.

[0030] In this embodiment, the waterproof box is fixed by four fixing bolts. The connection line of the four fixing bolts is a rectangle. Then the number of fixing positions is four. Specifically, the fixing frame 1 is an I-shaped frame. The I-shaped frame includes two parallel cross beams 11 and a longitudinal beam 12 connecting the two cross beams 11. Two fixing positions are provided on each cross beam 11, and the connection line of the four fixing positions is a rectangle adapted to the connection line of the four fixing bolts. On the one hand, this can facilitate the setting of four fixing positions. On the other hand, the vertical beam can be used as a handle to facilitate the operation of the staff.

[0031] Of course, in other embodiments, the number of fixing positions can be set according to the actual requirements of the waterproof box. For example, if the number is six, the connection line of each fixing position can be a hexagon. Then the whole fixing frame 1 can be in a disc or polygonal plate-like structure, and the fixing positions are distributed at the corresponding positions of the plate-like structure according to the actual design positions. Or the number of fixing positions can be eight. At this time, the fixing positions are distributed at the corresponding positions of the plate-like structure according to the actual design positions.

[0032] The using process of the mounting bracket of the present application is as follows:

[0033] During actual use, first rotate the handle 5 to make the fixing screw 2 protrude forward in the threaded through hole 3, and the forward protrusion distance is about 4 / 5 of the depth of the threaded inner hole 41 of the fixing stud 4 for mounting the waterproof box. Then put the fixing stud 4 on the front end of the fixing bolt and rotate the fixing stud 4 until the fixing stud 4 is tightly attached to the fixing frame 1. After all four fixing studs 4 are installed according to the above steps, on the one hand, each fixing stud 4 is perpendicular to the fixing frame 1, and on the other hand, the end surface facing away from the fixing frame 1 is coplanar.

[0034] Hold the fixing frame 1 and align the bottoms of the four fixing studs 4 with the pre-drawn positioning points for spot welding. The four fixing studs 4 are spot welded in a diagonal manner at one time, and then full welding is performed. After the welding is completed and the welded part is cooled, rotate the handle 5 in turn to withdraw the fixing screw 2 and remove the mounting bracket.

[0035] In summary, the mounting bracket of the present utility model can well solve the problem that the distance between the fixing studs 4 does not conform to the designed distance due to displacement during the welding of the fixing studs 4 of the waterproof box of the offshore wind turbine acquisition device, and ensure the reliability of the installation of the waterproof box.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
