Description

Technical Field

[0001] This utility model relates to the field of magnetic base installation technology, and more specifically, to a magnetic base structure for installing a monitoring sensor in a wind turbine. Background Technology

[0002] During wind turbine operation, monitoring sensors are needed to collect real-time equipment operating data (such as vibration and temperature) to ensure the safe and stable operation of the unit. The installation stability of the sensors directly affects the accuracy and reliability of the monitoring data. Current technologies often have several shortcomings in the installation structures of wind turbine monitoring sensors: some installation structures rely on rigid connections such as bolts, which are cumbersome to install and disassemble, requiring multiple tools and time, making them unsuitable for rapid maintenance under complex wind turbine operating conditions; while some magnetic installation structures simplify the installation process, the permanent magnet fixing method is not stable enough, and long-term vibration of the unit can cause the permanent magnet to shift or fall off, thus affecting the magnetic attraction effect; at the same time, most installation structures lack effective buffering and limiting designs. Under the vibration transmitted by the wind turbine operation, this can easily cause wear between the sensor and the installation structure, and may also lead to sensor positional displacement, reducing monitoring accuracy. In addition, the assembly flexibility between the various components of the installation structure is insufficient, making it difficult to easily adjust according to the sensor installation requirements and adapt well to different installation scenarios of the wind turbine. These problems all adversely affect the stable operation and maintenance efficiency of wind turbine monitoring sensors. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a magnetic base structure for installing monitoring sensors in wind turbine units. It aims to improve the problem that some installation structures rely on rigid connection methods such as bolts, which not only make the installation and disassembly process cumbersome, require multiple tools and consume a lot of time, but also make it difficult to meet the needs of rapid maintenance under the complex operating conditions of wind turbine units.

[0004] This utility model is implemented as follows: A magnetic base structure for a wind turbine monitoring sensor includes a magnetic base body and a mounting base. The magnetic base body has an internal mounting cavity for accommodating a permanent magnet. A cover plate is bolted to the open end of the mounting cavity. The mounting base is L-shaped and a limiting block is fixedly mounted at one end. The limiting block is T-shaped. A limiting groove matching the limiting block is provided on one side of the magnetic base body, and the top of the limiting groove is open. A first groove is provided on one side of the limiting block. A first spring is symmetrically fixedly mounted on one side of the inner wall of the first groove. A plug is fixedly mounted at one end of the first spring. A slot matching the plug is provided on one side of the inner wall of the limiting groove. An adjustment component is mounted on one side of the plug. The sensor body is fixedly mounted at the other end of the mounting base.

[0005] In a preferred embodiment of this utility model, a buffer pad is fixedly installed on one side of the magnetic base body. The buffer pad is glued to one side of the magnetic base body, and the thickness of the buffer pad is 2-5mm.

[0006] In a preferred embodiment of this utility model, the bottom end of the insert is inclined, and a second groove is provided on one side of the insert. The first spring is symmetrically fixed between the second groove and the inner wall of the first groove.

[0007] In a preferred embodiment of this utility model, a support rod is symmetrically fixedly installed on one side of the inner wall of the second groove. One end of the support rod slides through the limiting block and is inserted into the mounting base. A circular groove matching the support rod is provided on one side of the mounting base. The support rod is slidably connected to the inner wall of the circular groove. The depth of the circular groove is greater than the length of the support rod.

[0008] In a preferred embodiment of this utility model, a first pull rod is fixedly installed on one side of the inner wall of the second groove, a second pull rod is installed at one end of the first pull rod, and a pull plate is installed at one end of the second pull rod. The first pull rod and the second pull rod have the same diameter, and the mounting base is provided with a circular hole that matches the first pull rod and the second pull rod.

[0009] In a preferred embodiment of this utility model, the outer side of the pull plate is provided with an external thread, one side of the mounting base is provided with a threaded groove that matches the pull plate, one side of the pull plate is provided with a pull groove, a crossbar is installed on the inner wall of the pull groove, and the threaded groove communicates with the circular hole.

[0010] In a preferred embodiment of this utility model, a guide cavity is provided inside the second pull rod, a circular plate is slidably installed on the inner wall of the guide cavity, a guide rod is fixedly installed on one side of the circular plate, one end of the guide rod slides through the second pull rod and is fixedly connected to one end of the first pull rod, and the diameter of the circular plate is larger than the diameter of the guide rod.

[0011] In a preferred embodiment of this utility model, a clamping cavity is provided at the bottom end of the magnetic base body, and a second spring is symmetrically fixedly installed at the bottom end of the clamping cavity. A first circular block is fixedly installed at the top end of the second spring, and a top rod is fixedly installed on the first circular block. The top end of the top rod slides through the magnetic base body and is fixedly installed on the second circular block. A circular groove matching the second circular block is provided at the bottom end of the inner wall of the limiting groove, and the top end of the second circular block abuts against the bottom end of the limiting block.

[0012] The beneficial effects of this utility model are as follows: This utility model achieves magnetic fixation through the permanent magnet inside the magnetic base body. With the help of bolts and cover plates, the permanent magnet is stably limited. This can quickly adsorb the installation structure onto the metal surface of the wind turbine, simplifying the installation process, and also prevent the permanent magnet from shifting or falling off, ensuring the stability of the magnetic attraction. At the same time, the buffer pad (2-5mm thick, glued) on one side of the magnetic base body can effectively reduce the friction and vibration transmission between the installation surface and the magnetic base, reducing the impact of vibration on the sensor monitoring accuracy.

[0013] The mounting base and the magnetic base body are initially positioned by the cooperation of the T-shaped limiting block and the limiting groove. Then, the first spring pushes the insert block into the slot to complete the fixation. With the auxiliary limiting of the support rod and the circular groove, the stability of the connection between the two is greatly improved. Moreover, the adjusting component consisting of the first pull rod, the second pull rod, and the pull plate can be easily pulled out of the slot to achieve disassembly. At the same time, the circular plate and guide rod inside the second pull rod can ensure the stability of the pull rod's movement direction. The pull plate can be screwed into the threaded groove for storage, which takes into account both the reliability of the installation and the convenience of disassembly and adjustment.

[0014] The second spring inside the clamping cavity at the bottom of the magnetic base body pushes the second round block against the bottom of the limiting block through the first round block and the top rod, further enhancing the fit between the limiting block and the limiting groove, reducing the gap between components, reducing the risk of component loosening caused by wind turbine vibration, ensuring that the sensor body always maintains a stable installation position, ensuring the accuracy of monitoring data, and the overall structure is adapted to the complex working conditions of wind turbines, improving the efficiency of sensor installation and maintenance.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a magnetic base structure for a wind turbine monitoring sensor, including a magnetic base body 110 and a mounting base 120. The magnetic base body 110 has an internal mounting cavity for accommodating a permanent magnet 111. A cover plate 113 is installed at the open end of the mounting cavity by bolts 112. The mounting base 120 is L-shaped and a limiting block 130 is fixedly installed at one end. The limiting block 130 is T-shaped. A limiting groove matching the limiting block 130 is provided on one side of the magnetic base body 110, and the top of the limiting groove is open. A first groove is provided on one side of the limiting block 130. A first spring 131 is symmetrically fixedly installed on one side of the inner wall of the first groove. A plug 132 is fixedly installed at one end of the first spring 131. A slot matching the plug 132 is provided on one side of the inner wall of the limiting groove. An adjustment component is installed on one side of the plug 132. A sensor body 140 is fixedly installed at the other end of the mounting base 120.

[0025] In some specific implementations, a buffer pad 170 is fixedly installed on one side of the magnetic base body 110. The buffer pad 170 is bonded to one side of the magnetic base body 110 with adhesive, and its thickness is 2-5mm. The buffer pad 170 can directly buffer the vibration transmission between the magnetic base body 110 and the wind turbine mounting surface, preventing vibration from directly acting on the entire mounting structure. At the same time, the buffer pad 170 can reduce the hard friction between the magnetic base body 110 and the mounting surface, protecting both surfaces from damage, indirectly extending the service life of the magnetic base body 110 and the mounting surface, and further ensuring the stability of the monitoring environment of the sensor body 140.

[0026] In some specific implementations, the bottom of the insert 132 is inclined, requiring no additional operation. The inclined surface can directly contact the opening of the limiting groove and compress the first spring 131, allowing the insert 132 to automatically adapt to the insertion path of the limiting groove, simplifying the installation steps. Furthermore, a second groove is provided on one side of the insert 132, and the first spring 131 is symmetrically fixed between the second groove and the inner walls of the first groove, ensuring that the insert 132 can be smoothly inserted into the slot.

[0027] In some specific implementations, a support rod 133 is symmetrically fixedly installed on one side of the inner wall of the second groove. One end of the support rod 133 slides through the limiting block 130 and is inserted into the mounting base 120. A circular groove matching the support rod 133 is provided on one side of the mounting base 120. The support rod 133 is slidably connected to the inner wall of the circular groove. The depth of the circular groove is greater than the length of the support rod 133, which provides sufficient sliding space for the support rod 133. The length of the support rod 133 will not limit the compression stroke of the insert 132, ensuring that the insert 132 can be completely disengaged from the slot and will not affect the disassembly of the mounting base 120.

[0028] Please see Figure 4 and Figure 5 A first pull rod 150 is fixedly installed on one side of the inner wall of the second groove. A second pull rod 151 is installed at one end of the first pull rod 150, and a pull plate 152 is installed at one end of the second pull rod 151. The first pull rod 150 and the second pull rod 151 have the same diameter, and the mounting base 120 is provided with a round hole that matches the first pull rod 150 and the second pull rod 151. This ensures the stability of the pull rods during movement and prevents them from wobbling due to diameter differences, ensuring smooth disassembly. The pull plate 152 has an external thread on its outer side, and a threaded groove matching the pull plate 152 is provided on one side of the mounting base 120. A pull groove is provided on one side of the pull plate 152, and a crossbar is installed on the inner wall of the pull groove. The threaded groove communicates with the round hole. The crossbar provides a force point for pulling the pull plate 152. Even in confined spaces, the pull plate 152 can be easily pulled by the crossbar, improving the convenience of disassembly. At the same time, the threaded groove communicates with the round hole, ensuring that the second pull rod 151 can smoothly pass through and connect with the pull plate 152.

[0029] In some specific implementations, a guide cavity is provided inside the second pull rod 151. A circular plate 153 is slidably installed on the inner wall of the guide cavity. A guide rod 154 is fixedly installed on one side of the circular plate 153. One end of the guide rod 154 slides through the second pull rod 151 and is fixedly connected to one end of the first pull rod 150. The diameter of the circular plate 153 is larger than the diameter of the guide rod 154, which can prevent the guide rod 154 from coming out of the guide cavity of the second pull rod 151, ensuring the reliability of the connection between the first pull rod 150 and the second pull rod 151, and avoiding the disassembly operation being affected by the pull rod coming off.

[0030] Please see Figure 6 The magnetic base body 110 has a clamping cavity at its bottom end. A second spring 160 is symmetrically fixedly installed at the bottom end of the clamping cavity. A first circular block 161 is fixedly installed at the top end of the second spring 160. A top rod 162 is fixedly installed on the first circular block 161. The top end of the top rod 162 slides through the magnetic base body 110 and is fixedly installed with a second circular block 163. A circular groove matching the second circular block 163 is provided at the bottom end of the inner wall of the limiting groove. The top end of the second circular block 163 abuts against the bottom end of the limiting block 130. This limits the position of the limiting block 130, ensuring the stability of its installation position and indirectly guaranteeing the installation accuracy of the sensor body 140, thus improving the accuracy of the monitoring data.

[0031] Working principle: First, the magnetic base body 110 generates magnetic force through the permanent magnet 111 in the internal mounting cavity, which can quickly attract it to the metal mounting surface of the wind turbine. The buffer pad 170 (2-5mm thick, glued) on one side of the magnetic base body 110 can reduce friction and vibration transmission between the mounting surface and the magnetic base. The permanent magnet 111 is fixed to the cover plate 113 at the opening end of the mounting cavity by bolts 112 to limit its position and ensure stable magnetic attraction performance.

[0032] Next, the mounting base 120 and the magnetic base body 110 are assembled: the mounting base 120 is L-shaped, and a T-shaped limiting block 130 fixed at one end is inserted into the limiting groove at the top opening on one side of the magnetic base body 110. During the insertion process, the first spring 131 in the first groove on one side of the limiting block 130 pushes the insert 132 (the bottom end is inclined, and there is a second groove on one side, with the first spring 131 fixed between the second groove and the inner wall of the first groove), so that the insert 132 is inserted into the slot in the inner wall of the limiting groove. At the same time, the support rod 133 in the limiting block 130 (fixed to the inner wall of the second groove) slides into the circular groove of the mounting base 120 (the depth is greater than the length of the support rod), completing the initial fixation. If disassembly is required, it can be performed by adjusting the components: pulling the pull plate 152 (with external threads on the outside and a groove with a crossbar on one side) will drive the second pull rod 151 and the first pull rod 150 (both with the same diameter, passing through the circular hole of the mounting base 120). The first pull rod 150 will pull the insert block 132 to compress the first spring 131, causing the insert block 132 to disengage from the slot. In the guide cavity inside the second pull rod 151, the circular plate 153 (with a diameter larger than the guide rod 154) moves with the first pull rod 150. The guide rod 154 ensures the stability of the pull rod's movement direction. After disassembly, the pull plate 152 can be screwed into the threaded groove (connected to the circular hole) of the mounting base 120 for storage. In addition, the second spring 160 in the clamping cavity at the bottom of the magnetic base body 110 pushes the first circular block 161, causing the push rod 162 to drive the second circular block 163 (located in the circular groove at the bottom of the inner wall of the limiting groove) to press upward against the bottom of the limiting block 130, enhancing the connection stability.

[0033] Finally, the sensor body 140 is fixed at the other end of the mounting base 120. The sensor body 140 is fixed to the mounting base 120 by magnetic attraction of the magnetic base body 110 and the limiting structure of the mounting base 120, so as to achieve stable installation of the sensor body 140 on the wind turbine and ensure normal monitoring function.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
