Description

Technical Field

[0001] The present invention relates to the technical field of electric power automation, and in particular to a fixing device for a wind power box transformer monitoring unit. Background Art

[0002] The fixing device of the wind turbine box transformer monitoring unit not only ensures the stable installation of the monitoring unit in the wind power generation environment, prevents displacement or damage caused by vibration, impact and severe weather conditions, but also provides anti-seismic protection, reduces the impact of mechanical stress on internal electronic components, and extends the life of the equipment; at the same time, by adopting a sealed design and waterproof materials, moisture and dust are prevented from entering, ensuring the safety and reliability of electrical connections, and maintaining high-precision data acquisition and control system performance; in addition, the fixing device optimizes space utilization, supports rapid installation and disassembly, simplifies the maintenance process, reduces labor costs and operating difficulties, enhances the weather resistance and reliability of the overall system, and ensures the efficient operation and long-term stable operation of the wind power generation system, ultimately improving operational efficiency and economic benefits, and ensuring the safe and reliable operation of equipment in various complex environments.

[0003] Some existing wind turbine box transformer monitoring units rely on the coordinated cooperation of bolts and angle plates to fix the wind turbine box transformer monitoring units on the fixing columns. However, because bolts are introduced, professional tools are required to tighten the bolts to fix the angle plates and the wind turbine box transformer monitoring units. It takes a lot of time to tighten the bolts, which reduces the installation efficiency and increases the labor intensity of the staff. Frequent disassembly and assembly can easily cause thread wear or damage, affecting the fixing effect and may even cause the risk of loosening or falling off.

[0004] Moreover, some wind turbine box transformer monitoring units are fixed to the angle plate by bolts, and the angle plate is fixed to the fixing column by bolts. This rigid connection cannot buffer the wind turbine box transformer monitoring unit. When a car passes near the fixing column, the wind turbine box transformer monitoring unit will vibrate. The vibration of the wind turbine box transformer monitoring unit will loosen the connection of the internal electronic components, causing poor contact or short circuit, thereby reducing the service life of the internal electronic components of the wind turbine box transformer monitoring unit.

[0005] At the same time, the air vents of the wind turbine box transformer monitoring unit are opened on both sides of the wind turbine box transformer monitoring unit, and rainwater can easily enter the interior of the wind turbine box transformer monitoring unit, seriously affecting the normal operation of the internal electronic components and further reducing the service life of the internal electronic components.

[0023] like Figure 1-10As shown, a wind turbine box transformer monitoring cabinet 3 is arranged inside the fixed frame 1, and a plurality of fixed blocks 19 and dampers 38 are fixedly connected to the top and bottom of the wind turbine box transformer monitoring cabinet 3, the inner surfaces of the plurality of fixed blocks 19 are movably embedded with rotating rods 1 20, the outer surfaces of the plurality of rotating rods 1 20 are fixedly installed with connecting plates 21, and the side of the plurality of connecting plates 21 away from the plurality of rotating rods 1 20 is fixedly installed with rotating rods 22, the outer surfaces of the plurality of rotating rods 22 are movably sleeved with sliders 23, the outer surfaces of the plurality of sliders 23 are fixedly connected with springs 24, the plurality of sliders 23 are divided into four groups, and the inner surfaces of the four groups of sliders 23 are movably embedded with fixed rods 25, the outer surface of the wind turbine box transformer monitoring cabinet 3 is fixedly connected with a plurality of sliders and slide bars 3 26, and a sliding groove 27 is provided on the side of the fixed frame 1 close to the plurality of slide bars 3 26, which enhances the structural stability of the wind turbine box transformer monitoring cabinet 3 to a certain extent, ensures that the wind turbine box transformer monitoring cabinet 3 can still work normally in harsh environments, ensures the stable operation of the equipment, and improves the service life of the equipment.

[0024] like Figure 1-10 As shown, a motor 28 is arranged at the bottom of the wind turbine box transformer monitoring cabinet 3, and a plurality of connecting blocks 29 are fixedly connected to the outer surface of the motor 28, and bolts 30 are movably embedded in the inner surfaces of the plurality of connecting blocks 29, and the motor 28 is provided with a rotating shaft 2 31 through the output shaft, and a plurality of fan blades 32 are fixedly installed on the outer surface of the rotating shaft 2 31, a plurality of air inlet holes 1 33 are provided at the bottom of the fixed frame 1, a plurality of air inlet holes 2 34 are provided at the bottom of the wind turbine box transformer monitoring cabinet 3, a plurality of exhaust holes 2 35 are provided on the outer surface of the fixed frame 1, and a plurality of exhaust holes 1 36 are provided on one side of the wind turbine box transformer monitoring cabinet 3 close to the plurality of exhaust holes 2 35, thereby further preventing rainwater from entering the interior of the wind turbine box transformer monitoring cabinet 3, preventing short circuit and corrosion of the internal circuit of the wind turbine box transformer monitoring cabinet 3, ensuring safe and reliable operation of the equipment, extending the service life of the equipment, reducing the equipment maintenance cost, and ensuring the safety of the operator.

[0025] like Figure 1-10 As shown, a rain shield 37 is fixedly connected to the outer surface of the fixed frame 1 near the top. The rain shield 37 can reduce the possibility of rainwater entering the wind turbine box transformer monitoring cabinet 3 when employees use the equipment, thereby increasing the service life of the wind turbine box transformer monitoring cabinet 3.

[0026] like Figure 1-10 As shown, two clockwork springs 9 are fixedly connected to the inner walls of two slots 4, a plurality of slide bars 12 are movably embedded in the inner surfaces of a plurality of slots 3 6, and a plurality of slide bars 2 13 are movably embedded in the inner surfaces of a plurality of slots 2 5. The slots 2 5 can limit the moving trajectory of the slide bars 2 13, thereby preventing the slide bars 2 13 from derailing and affecting the normal use of the wind turbine box transformer monitoring cabinet 3.

[0027] like Figure 1-10As shown, multiple slide bars 26 are movably embedded in the inner surfaces of multiple slide grooves 27, multiple springs 24 are evenly divided into four groups, and the four groups of springs 24 are movably sleeved on the outer surfaces of multiple fixed bars 25. Multiple fixed bars 25 and springs 24 are fixedly connected to the inner wall of the fixed frame 1, and multiple dampers 38 are fixedly connected to the inner top and bottom slide grooves 27 of the fixed frame 1 to limit the moving trajectory of the slide bar 3 26, thereby avoiding the derailment of the slide bar 3 26 and affecting the normal use of the equipment.

[0028] like Figure 1-10 As shown, multiple exhaust holes 2 35 and exhaust holes 1 36 are opened obliquely upward, and multiple bolts 30 are threadedly connected to the wind turbine box transformer monitoring cabinet 3. The bolts 30 can fix the motor 28 at the bottom of the wind turbine box transformer monitoring cabinet 3, providing a good working environment for the motor 28.

[0029] Working principle: This device is a fixing device for the wind turbine box transformer monitoring unit. The connection block 29 and the bolt 30 can be used to fix the motor 28 at the bottom of the wind turbine box transformer monitoring cabinet 3, providing a good working environment for the motor 28. The slide bar 26 and the slide groove 27 can be used to prevent the wind turbine box transformer monitoring cabinet 3 from being displaced due to vibration, thereby ensuring the stable operation of the equipment. The rain shield 37 can reduce the possibility of rainwater entering the wind turbine box transformer monitoring cabinet 3 when employees use the equipment.

[0030] When in use, the fixed frame 1 is brought close to the fixed column 2, and then two people pull the handle 18 at the same time, the handle 18 drives the tooth plate 10 and the limit plate 11 to move through the clamping plate 14, the tooth plate 10 and the limit plate 11 respectively drive the slide bar 12 and the slide bar 2 13 to move on the inner surfaces of the slot 3 6 and the slot 2 5, and when the tooth plate 10 moves, the gear 8 drives the shaft 1 7 inside the slot 1 4 to rotate, the rotation of the shaft 1 7 causes the spring 9 to deform, so that the spring 9 has elastic potential energy, and then the clamping plate 14 is brought close to the fixed column 2. The side of the fixed column 2 is moved, and the dovetail groove 15 and the dovetail groove 2 16 are overlapped, and then the handle 18 is released. At this time, the spring 9 releases the elastic potential energy, so that the groove 1 4 drives the gear 8 to rotate in the opposite direction, and then the toothed plate 10 drives the clamping plate 14 to move in the opposite direction, so that the clamping plate 14 is clamped on the surface of the fixed column 2 to achieve rapid clamping and fixing, and then the dovetail tenon 17 is inserted into the dovetail groove 15 and the dovetail groove 2 16, and the mortise and tenon structure is used to further fix the fixed frame 1 on the fixed column 2, thereby improving the stability of the fixed frame 1.

[0031] The fixing frame 1 and the fixing column 2 are quickly fixed by using the clamping plate 14, and then the fixing frame 1 and the fixing column 2 are further fixed by using the mortise and tenon structure, thereby avoiding thread damage caused by multiple disassembly and assembly, providing a stable and adjustable fixing effect, maintaining the integrity of the installation surface, and simplifying the maintenance and adjustment process.

[0032] When a vehicle passes by, the wind turbine box transformer monitoring cabinet 3 will vibrate and tend to move, and then the wind turbine box transformer monitoring cabinet 3 drives the rotating rod 20 to move through the fixed block 19, and the rotating rod 20 pulls the rotating rod 22 to move through the connecting plate 21, so that the rotating rod 22 drives the slider 23 to move on the outer surface of the fixed rod 25, and causes the spring 24 to deform, so that the spring 24 obtains elastic potential energy. When the vibration weakens, the spring 24 releases the elastic potential energy, so that the slider 23 moves to the initial position, and then indirectly moves the wind turbine box transformer monitoring cabinet 3 to the initial position, thereby achieving buffering of the wind turbine box transformer monitoring cabinet 3 and ensuring the reliability of the internal electrical connection of the wind turbine box transformer monitoring cabinet 3.

[0033] The spring 24 and the damper 38 are used to buffer and reduce shock of the wind turbine box transformer monitoring cabinet 3, which can effectively reduce the vibration and external impact generated during the operation of the equipment, protect the internal electronic components and sensitive equipment from mechanical stress damage, and extend the service life; at the same time, it reduces the noise caused by vibration, improves the working environment, ensures the reliability of electrical connections, and avoids faults and safety hazards caused by looseness. It is particularly suitable for monitoring cabinets containing precision sensors and control units, maintains high-precision data acquisition and control system performance, and ultimately extends the maintenance cycle and improves overall work efficiency and equipment reliability.

[0034] When the wind turbine box transformer monitoring unit is in use, heat will be emitted from the inside, and the motor 28 will be started. The motor 28 will drive the rotating shaft 2 31 to rotate through the output shaft. The rotating shaft 2 31 will apply kinetic energy to the air inside the wind turbine box transformer monitoring unit through the fan blades 32, so that the air moves upward, and then the air will enter the wind turbine box transformer monitoring unit from the air inlet 2 34, and then pass through the exhaust hole 2 35 to the exhaust hole 1 36 and then be discharged. Then, the inside of the wind turbine box transformer monitoring unit will present a slight negative pressure state, and then the outside air will enter through the air inlet 1 33 to realize air circulation, thereby ensuring that the wind turbine box transformer monitoring unit can operate at a normal temperature and improving the service life of the wind turbine box transformer monitoring unit.

[0035] The air inlet 33 is opened at the bottom of the fixed frame 1, which reduces the possibility of rainwater entering the wind turbine box transformer monitoring cabinet 3. In addition, the exhaust hole 2 35 is opened inclined upward, which further prevents rainwater from entering the wind turbine box transformer monitoring cabinet 3, prevents short circuit and corrosion of the internal circuit of the wind turbine box transformer monitoring cabinet 3, ensures safe and reliable operation of the equipment, extends the service life of the equipment, reduces the equipment maintenance cost, and ensures the safety of the operator.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
