Description

Technical Field

[0001] This utility model relates to the field of generator set monitoring technology, specifically to a wind turbine tower monitoring equipment installation device. Background Technology

[0002] The wind turbine tower is the "skeleton" and "base" of the wind turbine generator set. Its main function is to support the nacelle to the height required for power generation, and at the same time provide an installation carrier for auxiliary facilities such as cables, ladders, and platforms. It is a key structure to ensure the stable operation of the wind turbine and capture effective wind energy.

[0003] During the operation of wind turbine towers, attitude sensors are required to monitor the sway angle of the tower foundation in real time, thereby obtaining the stiffness and stress status of the tower and foundation.

[0004] In existing technologies, installing attitude sensors in wind turbine towers typically requires setting up an attitude sensor mounting device to fix the sensor inside the tower. However, due to the height of the wind turbine tower, when the attitude sensor malfunctions, workers need to climb to the top of the tower to replace it. This is not only labor-intensive but also affects the attitude sensor's real-time monitoring of the wind turbine tower's status. Although replacing a damaged attitude sensor located at the bottom is relatively convenient, the inability to replace it promptly also affects the attitude sensor's real-time monitoring of the wind turbine tower's status.

[0005] Therefore, we propose an installation device for wind turbine tower monitoring equipment to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an installation device for wind turbine tower monitoring equipment, in order to solve the problem mentioned in the background art that, due to the certain height of the wind turbine tower, when the attitude sensor malfunctions, the staff needs to climb to the top of the wind turbine tower to perform the replacement operation. This is not only labor-intensive, but also affects the real-time monitoring of the wind turbine tower status by the attitude sensor. Although it is easier to replace the attitude sensor located at the bottom, the inability to replace it in a timely manner will also affect the real-time monitoring of the wind turbine tower status by the attitude sensor.

[0007] This utility model provides the following technical solution: a wind turbine tower monitoring equipment installation device, including a tower body, with mounting protrusions fixedly installed on the inner walls of the upper and lower ends of the inner cavity of the tower body, and a motor fixedly installed on the bottom surface of the mounting protrusions, a circular turntable provided at the upper end of the mounting protrusions, and the output end of the motor passing through the mounting protrusions and fixedly installed at the bottom of the circular turntable, a number of attitude sensors evenly installed on the outer periphery of the top of the circular turntable, and a fixing component installed at the middle of the top of the circular turntable, and a number of protective plates fixedly installed on the upper side wall of the mounting protrusions.

[0008] Preferably, the circular turntable includes a main body and insert sleeves uniformly fixedly installed on the outer periphery of the top surface of the main body. A central sleeve is fixedly installed at the center of the top surface of the main body, and electrically conductive metal blocks are uniformly embedded and slidably installed on the bottom surface of the main body. The electrically conductive metal blocks are respectively positioned below the insert sleeves.

[0009] Preferably, the outer periphery of the disc body is uniformly provided with a plurality of square through holes, and the electrical metal blocks are respectively slidably disposed in the square through holes. A metal conductive block is fixedly installed in the upper inner cavity of the square through hole, and arc-shaped sliding grooves are respectively provided on the inner walls of the two sides of the inner cavity of the square through hole.

[0010] Preferably, a fixing round hole is provided on the inner outer wall of the insertion sleeve;

[0011] A threaded groove is provided at the center of the top surface of the middle sleeve, and several corresponding round holes are evenly provided on the outer circumference wall of the lower end of the middle sleeve, and the corresponding round holes are respectively set to the fixed round holes.

[0012] Preferably, a pair of ball bearings are respectively provided on the outer walls of both sides of the electrical metal block, and an inclined surface is provided at one end of the bottom surface of the electrical metal block.

[0013] Preferably, the fixing component includes a drive knob and a plurality of clamping pins that are slidably inserted between the fixing hole and the corresponding hole.

[0014] Preferably, the drive knob includes a threaded knob and a drive cylinder rotatably connected to the lower end of the threaded knob via a connecting bearing. The outer circumference of the drive cylinder is provided with a plurality of drive grooves corresponding to the insertion sleeve, and the inner walls on both sides of the inner cavity of the drive groove are provided with inclined arc-shaped grooves.

[0015] Preferably, driving balls are provided on both sides of one end of the clamping column, and the driving balls are respectively rolled in the inclined arc groove.

[0016] This utility model has the following beneficial effects:

[0017] When a powered attitude sensor malfunctions, staff can start the motor via a terminal device. The motor's output will drive a circular turntable to rotate. The turntable will move the attitude sensor adjacent to the malfunctioning sensor to the positive and negative poles on the top of the mounting protrusion. This removes the malfunctioning attitude sensor and moves the intact attitude sensor to the monitoring position, where it can then be powered on and put into operation. This method is not only convenient and quick to operate, saving manpower, but also ensures the real-time monitoring effect of the attitude sensor on the wind turbine tower.

[0024] 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.

[0025] Please see Figures 1-5An installation device for monitoring wind turbine towers includes a tower body 1. Mounting protrusions 2 are fixedly installed on the inner walls of the upper and lower ends of the inner cavity of the tower body 1. A motor 3 is fixedly installed on the bottom surface of the mounting protrusions 2. The motor 3 is electrically connected to a terminal device of the operator, so that the operator can remotely control the rotation of the motor 3. A circular turntable 4 is provided at the upper end of the mounting protrusions 2. The output end of the motor 3 passes through the mounting protrusions 2 and is fixedly installed at the bottom of the circular turntable 4 to drive the circular turntable 4 to rotate. Several attitude sensors 5 are evenly installed on the outer periphery of the top of the circular turntable 4. By setting the attitude sensors 5, the sway angle of the wind turbine tower foundation can be monitored in real time, thereby obtaining the stiffness and stress of the tower and foundation. A fixing component 6 is installed at the middle of the top of the circular turntable 4. The fixing component 6 is used to fix the attitude sensors 5 on the circular turntable 4. Several protective plates 7 are fixedly installed on the upper side wall of the mounting protrusions 2. Except for the outermost attitude sensor 5, the protective plates 7 are respectively set below the attitude sensors 5.

[0026] The circular turntable 4 includes a main body 41 and insertion sleeves 42 uniformly fixedly installed on the outer periphery of the top surface of the main body 41. Attitude sensors 5 are respectively inserted into the insertion sleeves 42. A central sleeve 43 is fixedly installed at the center of the top surface of the main body 41. Electrically conductive metal blocks 44 are uniformly embedded and slidably installed on the bottom surface of the main body 41. The electrically conductive metal blocks 44 are respectively positioned below the insertion sleeves 42. A plurality of square through holes 411 are uniformly arranged on the outer periphery of the main body 41. 4 are slidably disposed in the square through hole 411. A metal conductive block 412 is fixedly installed in the upper inner cavity of the square through hole 411. Arc-shaped sliding grooves 413 are respectively provided on the inner walls of both sides of the inner cavity of the square through hole 411. A fixed round hole 421 is provided on the inner outer wall of the insertion sleeve 42. A threaded groove 431 is provided at the middle of the top surface of the middle sleeve 43. Several corresponding round holes 432 are evenly provided on the outer peripheral wall of the lower end of the middle sleeve 43, and the corresponding round holes 432 are respectively provided corresponding to the fixed round holes 421.

[0027] The thickness of the electrically conductive metal block 44 is slightly greater than the distance between the metal conductive block 412 and the top surface of the mounting protrusion 2, thereby ensuring that the top and bottom surfaces of the electrically conductive metal block 44 can make tight contact with the metal conductive block 412 and the mounting protrusion 2, ensuring the energizing effect. A pair of ball bearings 441 are respectively provided on the outer walls of both sides of the electrically conductive metal block 44, and an inclined surface 442 is provided at one end of the bottom surface of the electrically conductive metal block 44. By providing the inclined surface 442, it is ensured that when the electrically conductive metal block 44 contacts the protective plate 7, it will be pressed into the square through hole 411 by the protective plate 7. Figure 4As shown, the positive and negative terminals on the electrical metal block 44 are electrically connected to the positive and negative terminals on the metal conductive block 412. At the same time, the positive and negative terminals on the metal conductive block 412 are electrically connected to the positive and negative terminals on the attitude sensor 5, respectively. The top of the mounting protrusion 2 is provided with positive and negative terminals that are electrically connected to the power supply. The positive and negative terminals of the electrical metal block 44 are electrically connected to the positive and negative terminals that are electrically connected to the power supply on the top of the mounting protrusion 2, thereby achieving the effect of powering the attitude sensor 5.

[0028] Specifically, when the powered attitude sensor 5 malfunctions, the operator can start the motor 3 through the terminal device. The output of the motor 3 will drive the disc body 41 to rotate. The disc body 41 will move the attitude sensor 5 adjacent to the malfunctioning attitude sensor 5 to the positive and negative positions set on the top of the mounting protrusion 2. This will remove the malfunctioning attitude sensor 5 and move the intact attitude sensor 5 to the monitoring position and power it on. This is not only convenient and quick to operate, saving manpower, but also ensures the real-time monitoring effect of the attitude sensor 5 on the wind turbine tower.

[0029] Furthermore, in the initial state, the attitude sensor 5 located at the positive and negative terminals on the top of the mounting protrusion 2 will perform normal power-on monitoring, while the electrical metal blocks 44 located below the attitude sensors 5 in other positions will be stored in the protective plate 7, thereby protecting the electrical metal blocks 44.

[0030] When the main body 41 of the disk rotates, the adjacent electrically conductive metal blocks 44 will be squeezed into the square through hole 411 under the action of the inclined surface 442, thereby completing the subsequent power transmission effect.

[0031] Please see Figure 2 and Figure 3 The fixing component 6 includes a drive knob 61 and a plurality of clamping pins 62 that are respectively slidably inserted between the fixing round hole 421 and the corresponding round hole 432.

[0032] The drive knob 61 includes a threaded knob 611 and a drive cylinder 613 rotatably connected to the lower end of the threaded knob 611 via a connecting bearing 612. The output end of the threaded knob 611 is threadedly installed in the threaded groove 431. The outer circumference of the drive cylinder 613 is provided with a plurality of drive grooves 614 corresponding to the insertion sleeve 42. The inner walls on both sides of the inner cavity of the drive groove 614 are respectively provided with inclined arc grooves 615.

[0033] Drive balls 621 are respectively provided on both sides of one end of the clamping column 62, and the drive balls 621 are respectively rolled in the inclined arc groove 615.

[0034] Specifically, when the operator needs to install the attitude sensor 5 on the circular turntable 4, the lower end of the attitude sensor 5 can be inserted into the insertion sleeve 42. Then, by rotating the threaded knob 611, the threaded knob 611 will drive the drive cylinder 613 to move down. Under the restraint of the inclined arc groove 615 and the drive ball 621, the outer end of the clamping column 62 can be pressed against the outer wall of the attitude sensor 5, thereby achieving the fixing effect of multiple attitude sensors 5. The operation is convenient and quick, and the installation efficiency is high.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
