[0002] A wind turbine is a system that converts wind energy into electrical energy. It includes a wind rotor, a nacelle, and a tower. The wind rotor contains blades, a hub, and reinforcements. It has functions such as the blades rotating under wind power to generate electricity and the generator head rotating. The transmission mechanism of a wind turbine consists of a main shaft, a gearbox, and a generator. If the transmission mechanism is abnormal, it will reduce the efficiency of power conversion and cause power loss, or even completely fail to operate normally, requiring a long downtime and high costs for repairs, increasing the cost of use. At present, the transmission system in wind turbines is monitored by a vibration monitoring system, and the operating status of the transmission mechanism of the unit is monitored and analyzed through vibration data. When abnormal vibration data appears, early warning can be detected and early warning can be given to reduce maintenance losses. The vibration monitoring system monitors each part of the unit's transmission mechanism through a number of sensors of various specifications, and transmits the vibration signal back to the collector, and uploads the data to the booster station collection server through the collector for visual monitoring. Currently, when installing the collector in a wind turbine, in order to ensure the stability of the collector installation, it is necessary to apply thread fastener on the connecting bolts to reduce the displacement of the collector caused by loose bolts and reduce the stability of the monitoring system.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a collector installation structure of an intelligent vibration monitoring system for a wind turbine generator system, comprising a frame 1, a plurality of bolt holes 2 are penetrated at both ends of the surface of one side of the frame 1, an automatic gluing mechanism 3 is arranged at the position corresponding to each bolt hole 2 on the surface of the other side of the frame 1, each automatic gluing mechanism 3 comprises a containing box 301 for containing threaded fastener glue, the containing box 301 is integrally arranged with the frame 1, a connecting groove 302 connected with the corresponding containing box 301 is opened on the inner wall of one side of each bolt hole 2, a rubber sealing plug 311 is inserted at the opening of the connecting groove 302, a piston pressure plate 303 is slidably connected between the inner walls of the containing box 301, and the piston pressure plate 303 is connected to the trigger mechanism.

[0020] See also Figure 3 and Figure 4 The trigger mechanism includes a driven rod 304, one end of which is fixedly connected to the upper surface of the piston pressure plate 303, and the driven rod 304 is slidably connected to a through hole opened on the top surface of the accommodating box 301, and the other end of the driven rod 304 extends to the outside of the accommodating box 301 through the through hole and is fixedly connected to one side of the bottom surface of the connecting rod 305. A limit spring 308 is sleeved on the outside of the driven rod 304, and the two ends of the limit spring 308 are respectively fixedly connected to the top surface of the accommodating box 301 and the bottom surface of the connecting rod 305, and one end of the active rod 306 is fixedly connected to the other side of the bottom surface of the connecting rod 305, and the other end of the active rod 306 is fixedly connected to the trigger plate 307.

[0021] When in use, first remove the rubber sealing plug 311 in the corresponding bolt insertion hole 2 according to the installation requirements, and insert one end of the bolt into the corresponding bolt insertion hole 2. Because the width of the bolt head is greater than the width of the bolt insertion hole 2, the bolt head will contact the trigger plate 307 during the insertion of the bolt. As the bolt is inserted, the trigger plate 307 is gradually driven to move toward the frame 1, and the active rod 306 will also move accordingly. The driven rod 304 is driven by the connecting rod 305 to move synchronously, driving the piston pressure plate 303 to move downward inside the receiving box 301. Thereby, the thread fastener inside the housing box 301 can be pushed to penetrate from the connecting groove 302 into the bolt insertion hole 2. Since the bolt is inserted in a rotating manner during installation, the thread fastener will be evenly smeared on the outer wall of the bolt rod during the rotation process. After the bolt rod with the thread fastener is threadedly connected to the threaded hole or nut of the mounting part, the connection firmness can be improved, the loosening of the bolts due to external vibration force can be reduced, the stability of the installation of the collector of the vibration monitoring system can be ensured, and the connection lines between the collector and various sensors can be prevented from being disconnected due to displacement of the collector due to loosening of the bolts.

[0022] Furthermore, a surface of one side of the trigger plate 307 is in the same plane as the inner wall of one side of the corresponding bolt insertion hole 2 , and a plate groove 309 having a depth consistent with the thickness of the trigger plate 307 is opened on one side of each bolt insertion hole 2 and located on the surface of one side of the frame 1 .

[0023] The surface of one end of the trigger plate 307 and the edge of one side of the bolt insertion hole 2 are in the same vertical plane. Firstly, it can ensure that the bolt can contact the trigger plate 307 during the insertion process, and the trigger plate 307 drives the piston pressure plate 303 to extrude the thread fastener. Secondly, it can also prevent the trigger plate 307 from affecting the overall width of the bolt insertion hole 2 and reducing the specifications of the bolts used. When the bolts are installed in place, the trigger plate 307 is located in the plate groove 309 as a whole, and its two side surfaces form planes with the upper surface of the frame 1 and the inner wall of one side of the bolt insertion hole 2, thereby ensuring the stability of the bolt installation and preventing the bolts from being held by the trigger plate 307 and unable to be installed in place.

[0024] Furthermore, a sealing partition 310 is integrally provided between the inner walls of the containing box 301 and above the piston pressure plate 303. The sealing partition 310 divides the interior of the containing box 301 into a containing chamber and a sealing chamber. A sealing hole is provided on the surface of one side of the sealing partition 310. The driven rod 304 is connected to the piston pressure plate 303 through the sealing hole, and a sealing rubber ring is provided on the inner wall of the sealing hole.

[0025] By providing the sealing partition 310 , the overall sealing of the container box 301 can be improved, the leakage of thread fastening glue can be reduced, and the convenience in use can be improved.

[0026] Furthermore, a transparent viewing window is provided on a surface of the receiving box 301 which is away from the frame body 1 .

[0027] By providing a viewing window (not shown in the figure), it is convenient for the installer to observe the amount of thread fastening glue inside the receiving box 301, thereby improving convenience in use.

[0028] See also Figure 2 The frame 1 includes a straight frame 101 and an L-shaped frame 102. A plurality of bolt holes 2 are respectively provided on the surfaces of one end of the straight frame 101 and the L-shaped frame 102. The straight frame 101 and one end of the L-shaped frame 102 are arranged in parallel and have a height difference. One end of the straight frame 101 and one end of the L-shaped frame 102 are connected through an inclined connecting portion 103. The straight frame 101, the inclined connecting portion 103 and the L-shaped frame 102 are integrally formed.

[0029] The straight frame 101 and the L-shaped frame 102 are used to connect the installation part and the collector body respectively. When in use, more than two frames 1 are symmetrically distributed on both sides of the collector. Use bolts to first connect the L-shaped frame 102 to the collector, and then connect each straight frame 101 to a suitable installation position inside the wind turbine. After installation, there is a height difference between the straight frame 101 and the L-shaped frame 102, so there will be a gap between the collector and the installation position, which is convenient for ventilation and heat dissipation of the collector to maintain working stability. At the same time, the straight frame 101 and the L-shaped frame 102 are connected by the inclined connecting part 103 with a certain elasticity. When a strong external force acts on the collector, the overall structure of the frame 1 will also buffer the force to a certain extent.

[0030] Working principle: when in use, more than two frames 1 are symmetrically distributed on both sides or around the collector. Use bolts to first connect the L-shaped frame 102 to the collector, and then connect each straight frame 101 to the appropriate installation position inside the wind turbine. During the installation process, remove the rubber sealing plug 311 in the corresponding bolt hole 2 according to installation needs, and insert one end of the bolt into the corresponding bolt hole 2. During the process of rotating and inserting the bolt, the bolt head will contact the trigger plate 307 and drive it to move downward. At the same time, the piston pressure plate 303 will also synchronously move in the receiving box 301 to squeeze the thread fastener in the receiving cavity from the connecting groove 302 to the bolt hole 2, and cooperate with the rotation of the bolt to evenly apply it on the outer wall of the bolt rod. By automatically applying the thread fastener during the installation process, the convenience is improved without the need for manual application, and the firmness of the bolt connection is improved, thereby improving the stability of the collector installation in the vibration monitoring system.

[0031] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
