Description
Technical Field
[0001] This utility model relates to the field of protective equipment technology, and in particular to a blade bolt fracture prevention and impact monitoring device. Background Technology
[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source, making it very environmentally friendly. Furthermore, wind energy reserves are enormous, thus attracting increasing attention from countries worldwide. As the installed capacity of wind turbines in my country has been increasing year by year, after prolonged operation, the bolts connecting the blades and the hub frequently fail and break. After a bolt breaks, the broken bolt on the hub side detaches, which will likely damage components such as limit switches inside the hub.
[0003] Currently, most wind power equipment lacks fracture monitoring devices for blade bolts, making it impossible to detect bolt fractures in a timely manner and to accurately locate the specific location of the fractured bolt, thereby reducing the safety of equipment operation and the efficiency of maintenance. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a blade bolt fracture prevention and impact monitoring device.
[0005] An embodiment of this utility model provides a blade bolt fracture anti-impact monitoring device, comprising: Mounting frame; The mounting frame is provided with several monitoring components, including a mounting block, a pressure plate, a torsion spring, and a signal transmitter. The mounting block is fixedly mounted on the mounting frame and has a mounting groove. A shaft is fixedly mounted in the mounting groove and is rotatably connected to one end of the pressure plate. The two ends of the torsion spring are fixedly mounted on the shaft and the pressure plate, respectively. Contact points are fixedly provided on the mounting frame and at the bottom of the pressure plate. The signal transmitter is fixedly mounted on the mounting frame. Furthermore, the pressure plate is provided with an anti-smashing component, which includes a connecting rope and a pin. One end of the connecting rope is fixedly mounted on the pressure plate, and the pin is fixedly connected to the other end of the connecting rope. The pin is threaded, and a positioning nut is threadedly connected to the pin.
[0006] Furthermore, the blade bolt has a through hole, and the pin passes through the through hole.
[0007] Furthermore, the two contacts are configured correspondingly, and the signal transmitter is electrically connected to both contacts.
[0008] Furthermore, a rubber block is fixedly provided at the bottom of the pressure plate, and the rubber block is abutted against the bolt.
[0009] Furthermore, the mounting frame is arranged in a circular shape, and multiple mounting holes are provided through the mounting frame.
[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. A monitoring component is installed. When a bolt breaks, the pressure plate springs back to its original position due to loss of support, causing the two contacts to make contact with each other and thus connecting the circuit. Once the circuit is connected, the signal transmitter is immediately triggered and sends a wireless alarm signal to the monitoring system. After receiving the signal, the monitoring system can identify and locate the specific location of the broken bolt in real time, which facilitates timely detection and accurate location of abnormalities, effectively improving the safety of equipment operation and the efficiency of maintenance.
[0011] 2. An anti-smashing component is installed. When the blade bolt breaks, the connecting rope 10 and the pin 11 can hold it in place, preventing it from flying off and affecting the operation of other parts, thus improving safety.
[0012] In summary, this utility model incorporates a monitoring component that can promptly detect and accurately locate broken bolts, effectively improving equipment safety and maintenance efficiency; it also includes an anti-smashing component that can secure broken blade bolts, further enhancing safety.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0018] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a blade bolt fracture anti-impact monitoring device, including: Mounting frame 1 is arranged in a circular shape. Multiple mounting holes 9 are provided through the mounting frame 1. The mounting holes 9 are used to fix the mounting frame 1 on the mounting position of the blade bolt. The mounting position of the blade bolt is pre-threaded.
[0019] The monitoring component includes a mounting block 2, a pressure plate 3, a torsion spring 5, and a signal transmitter 8. The mounting block 2 is fixedly mounted on the mounting frame 1. The mounting block 2 is provided with a mounting groove, and a shaft 4 is fixedly mounted in the mounting groove. The shaft 4 passes through one end of the pressure plate 3 and is rotatably connected, so that the pressure plate 3 can rotate through the shaft 4.
[0020] A rubber block 7 is fixedly installed at the bottom of the pressure plate 3, and the rubber block 7 abuts against the bolt. The two ends of the torsion spring 5 are respectively fixed on the shaft 4 and the pressure plate 3, so that the pressure plate 3 can be elastically connected to the shaft 4 through the torsion spring 5.
[0021] Contact points 6 are fixedly installed on both the mounting frame 1 and the bottom of the pressure plate 3, with two corresponding contacts 6. When a bolt breaks, the pressure plate 3 springs back to its original position due to loss of support, causing the two contacts 6 to come into contact with each other, thereby connecting the circuit.
[0022] The signal transmitter 8 is fixedly installed on the mounting frame 1. The signal transmitter 8 is electrically connected to both contacts 6. Its function is to detect the connection status between the contacts 6. Once the two contacts 6 are in contact and connected, the signal transmitter 8 is immediately triggered and sends a wireless alarm signal to the monitoring system. After receiving the signal, the monitoring system can identify and locate the specific location of the broken bolt in real time, which makes it easier for staff to discover abnormalities in a timely manner and locate them accurately, effectively improving the response speed and accuracy of structural safety monitoring.
[0023] The pressure plate 3 is equipped with an anti-smashing component, which includes a connecting rope 10 and a pin 11. One end of the connecting rope 10 is fixedly mounted on the pressure plate 3, and the pin 11 is fixedly connected to the other end of the connecting rope 10. The connecting rope 10 is used to connect the pin 11 and the pressure plate 3.
[0024] The pin 11 is threaded, and a positioning nut 12 is threadedly connected to the pin 11. The positioning nut 12 is used to limit the position of the pin 11. A through hole 13 is provided on the blade bolt, and the pin 11 passes through the through hole 13. This allows the connecting rope 10 and the pin 11 to hold the blade bolt in place if it breaks, preventing it from splashing and affecting the operation of other components, thus improving safety.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
