Description

Technical Field

[0001] This utility model relates to the field of power generation tower technology, specifically a safety monitoring device for wind power generation tower structures that is easy to install. Background Technology

[0002] As the core load-bearing structure supporting the wind turbine unit, the attitude stability of the wind turbine tower directly affects the power generation efficiency and equipment safety. Tilt sensors are key devices for monitoring tower tilt, settlement, and other deformations, and must be permanently fixed to the outer wall or internal structure of the tower.

[0003] Currently, tilt sensors are generally fixed with bolts. During installation, multiple bolts need to be tightened one by one to achieve sensor positioning and locking. Frequent disassembly and assembly (such as during periodic calibration or sensor replacement) can easily lead to wear of the threaded holes at the mounting position. After long-term use, the locking force may decrease or even strip the threads, affecting the reliability of the monitoring data. Utility Model Content

[0004] The purpose of this invention is to provide a safety monitoring device for wind power generation tower structures that is easy to install, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A safety monitoring device for wind power generation tower structures that is easy to install, comprising:

[0007] The mounting base has a card slot on its front side, and an angle sensor is located at the end of the card slot away from the mounting base. A fixing mechanism is provided between the angle sensor and the card slot.

[0008] A rotating block is disposed on the outside of one side of the mounting base, and a locking mechanism is provided between the rotating block and the mounting base.

[0009] Preferably, the fixing mechanism includes a slot formed in the middle of the card holder and a T-shaped card block fixedly connected to the back of the tilt sensor, the T-shaped card block being inserted into the card holder from the top end downwards;

[0010] Preferably, an electrical connection terminal is fixedly connected to the bottom end of the tilt sensor;

[0011] Preferably, the locking mechanism includes a sliding groove inside the mounting base and a push plate slidably connected to the right side inside the sliding groove. A spring is fixedly connected between the push plate and the inner wall of the sliding groove. Several insert rods are fixedly connected to both ends of the push plate on the side away from the spring. Several slots matching the insert rods are opened at both ends of the T-shaped block.

[0012] Preferably, the locking mechanism further includes an eccentric wheel rotatably connected to the middle of the inner side of the sliding groove via a bearing. The outer circumference of the eccentric wheel slides in contact with the back of the push plate. The rotating block and the eccentric wheel are coaxially fixed via a transmission shaft. An operating wheel is fixedly connected to one end of the rotating block, and a locking screw is threaded to the other end. Two positioning holes are opened on the upper end of the mounting base near the rotating block.

[0013] Preferably, the two positioning holes are arranged at an angle with the center of the drive shaft.

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

[0015] 1. This easy-to-install safety monitoring device for wind power tower structures achieves rapid positioning and mechanical locking of tilt sensors through the insertion and engagement of T-shaped blocks and slots, as well as the locking engagement of plug rods and slots.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution:

[0024] A safety monitoring device for wind power tower structures that is easy to install includes a mounting base 1, a mounting bracket 2 on the front of the mounting base 1, an angle sensor 3 at the end of the mounting bracket 2 away from the mounting base 1, a fixing mechanism between the angle sensor 3 and the mounting bracket 2, the fixing mechanism including a slot 5 in the middle of the mounting bracket 2, and a T-shaped locking block 6 fixedly connected to the back of the angle sensor 3, the T-shaped locking block 6 being inserted into the mounting bracket 2 from the top downwards, an electrical connection terminal 7 fixedly connected to the bottom of the angle sensor 3, a rotating block 4 disposed on one side of the mounting base 1, and a locking mechanism between the rotating block 4 and the mounting base 1, the locking mechanism including a sliding groove 8 inside the mounting base 1, and a pusher slidably connected to the right side inside the sliding groove 8. A spring 10 is fixedly connected between the moving plate 9, the pushing plate 9 and the inner wall of the sliding groove 8. Several insert rods 11 are fixedly connected to both ends of the pushing plate 9 away from the spring 10. Several slots 12 matching the insert rods 11 are opened at both ends of the T-shaped block 6. The locking mechanism also includes an eccentric wheel 13 rotatably connected to the middle of the inner side of the sliding groove 8 through a bearing. The outer circumference of the eccentric wheel 13 slides in contact with the back of the pushing plate 9. The rotating block 4 and the eccentric wheel 13 are coaxially fixed through a transmission shaft. An operating wheel 15 is fixedly connected to the outside of one end of the rotating block 4, and a locking screw 16 is threaded to the other end. Two positioning holes 14 are opened on the upper end of the side of the mounting base 1 near the rotating block 4. The two positioning holes 14 are arranged at an angle with the center of the transmission shaft.

[0025] In this embodiment, the tilt sensor 3 is quickly positioned and mechanically locked by the insertion and engagement of the T-shaped card block 6 and the card slot 5, and the locking engagement of the insertion rod 11 and the slot 12. This avoids the problem of thread hole wear caused by frequent disassembly and assembly of the traditional bolt fixing method, and significantly improves the reliability and service life of the installation structure.

[0026] Furthermore, through the linkage design of the eccentric wheel 13 pushing the insertion rod 11, and the cooperation between the locking screw 16 and the positioning hole 14, the tilt sensor 3 can be quickly locked in a single action and double fixed, which simplifies the installation process and ensures the long-term stability of the sensor in a vibration environment, effectively improving the accuracy of the monitoring data.

[0027] Working principle: First, weld the mounting base 1 to the designated installation position on the wind power tower, and then operate to install the tilt sensor 3. During installation, align the T-shaped locking block 6 on its back with the slot 5 of the locking base 2 and insert it. After initially positioning the sensor, immediately rotate the operating wheel 15, which drives the eccentric wheel 13 to rotate through the transmission shaft. The eccentric wheel 13 pushes the push plate 9 to stretch the spring 10, so that the insertion rod 11 is fully inserted into the slot 12 of the T-shaped locking block 6 to achieve initial locking. Then, screw the locking screw 16 into the positioning hole 14 to completely fix the rotating block 4 to the mounting base 1.

[0028] It should be noted that in the specific implementation of this technical solution, the tilt sensor 3 can be configured with conventional MEMS tilt sensors, electrolyte tilt sensors, or fiber optic tilt sensors, etc., as described in the prior art. Although these types of sensors are not described in detail in the technical solution, they are measurement elements that can be conventionally selected by those skilled in the art according to actual monitoring needs. Their working principle and data output method follow the well-known technology in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the tilt sensor 3 is mainly used to monitor the change of the tilt angle of the tower, but its specific type and signal output method (such as 4-20mA analog signal, RS485 digital signal, or wireless transmission, etc.) can be adjusted according to production requirements, all of which fall within the reasonable extension range of this technical solution.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
