Description

Technical Field

[0001] This utility model relates to a monitoring device, specifically a monitoring device for wind power prediction, belonging to the field of wind power generation technology. Background Technology

[0002] Wind power forecasting technology is a key means to ensure the safe and stable operation of wind farms and their efficient grid connection and consumption. Its accuracy is highly dependent on the quality and reliability of the data collected by front-end meteorological monitoring equipment. With the continuous deterioration of the global climate and the intensification of the energy crisis, building a green and low-carbon new energy system has become a consensus among countries around the world. Wind energy, as one of the most abundant natural resources on Earth, has become an important direction for the development of new energy sources due to its clean, efficient, and renewable advantages. However, due to the inherent randomness, volatility, and irregular intermittency of wind energy, large-scale grid connection of wind power can impact the stability of the power system. Developing wind power forecasting technology is an effective means to solve the above problems. Real-time and accurate wind power forecasting helps to achieve a high proportion of new energy grid connection and consumption, thereby effectively ensuring the stable operation and real-time dispatch of the new power system. Accurate wind power forecasting first and foremost depends on the collection of high-quality meteorological data.

[0003] In the prior art, monitoring equipment for wind power prediction typically includes a micro-meteorological instrument and its mounting support structure. For example, a monitoring device for wind power prediction disclosed in announcement number CN217422711U includes a micro-meteorological instrument and a mounting base. The micro-meteorological instrument has a card at its bottom, and the mounting base includes a base plate and an annular shell. The micro-meteorological instrument is locked or unlocked by moving a locking plate to the top of the card through an operating lever. Although this structure facilitates the quick assembly and disassembly of the sensor, its mounting base is only connected to the ground through multiple fixing ears on the outer wall of the base plate. It lacks a stable support structure that penetrates deep into the soil. In the open and windy environment of wind farms, long-term use can easily cause the equipment to sway or even overturn due to wind force, affecting the stability of data acquisition. For example, a wind farm wind power prediction device disclosed in announcement number CN220190470U includes a signal transmission structure and a mounting box. The mounting box contains a battery and a signal transmitter, while the outside of the mounting box has a mounting bracket for mounting solar panels. This device focuses on signal transmission and power supply functions, but its fixing method mainly relies on the mounting box and bottom structure for placement or simple fixation. It also suffers from unstable grounding and insufficient wind resistance, making it difficult to adapt to complex terrain and severe weather conditions in the field. In addition, the sensor height adjustment methods of existing monitoring equipment are relatively simple, mostly using a fixed height or only allowing for rough adjustment through simple telescopic rods. It cannot flexibly change the measurement height according to terrain undulations, vegetation height, or obstacle obstruction. Moreover, the adjustment process often requires multiple people or the use of tools, making it inconvenient to operate and inefficient. Utility Model Content

The frame assembly below the micro meteorological instrument serves as a basic support platform, providing a mounting base for other components. The fixed support assembly securely fixes the equipment to the ground, ensuring its stability in harsh environments such as strong winds and preventing tipping or displacement. The lifting and adjusting assembly allows for flexible vertical height adjustment of the micro meteorological instrument to adapt to the influence of different terrains, vegetation, or obstacles on the wind measurement height, ensuring the sensor is always in the optimal measurement position, thereby obtaining more representative meteorological data.

[0018] 2. The fixed support assembly of this utility model includes a drive unit, a vertical insert rod, and multiple diagonal bracing units. The vertical insert rod is connected directly below the synchronous drive unit, and the multiple diagonal bracing units are connected to the sides of the drive unit. The diagonal bracing units are located at the center of the four sides of the frame assembly.

The vertical insert rod is inserted vertically into the ground and primarily bears vertical tensile and compressive loads, providing tensile and compressive resistance. Capabilities; Multiple diagonal bracing units are distributed in the middle of the four sides of the frame assembly, inserted into the ground at an angle, providing lateral support from four directions, enhancing the equipment's wind resistance and overall anti-overturning stability; The drive unit enables all the inserted rods to move synchronously, avoiding the tedious installation of one by one, greatly improving on-site installation efficiency, saving manpower and time costs, and forming a multi-point support structure that allows the equipment to remain vertical and stable on uneven ground, adapting to complex terrain, effectively resisting horizontal wind force and vertical load, and ensuring that the micro-weather instrument can still work reliably in severe weather;

[0019] 3. The lifting and adjusting assembly of this utility model includes a threaded lifting outer tube, a threaded sleeve, a lifting square tube, and a lifting rod. The micro-meteorological instrument is fixed to the top of the lifting square tube. The threaded lifting outer tube and the threaded sleeve are threadedly connected. The lifting square tube is movably inserted into the threaded lifting outer tube. Part of the lifting rod is threadedly connected to the lifting square tube, and the rod penetrates the bottom end face of the threaded lifting outer tube. The lifting rod drives the threaded lifting outer tube and the lifting square tube to move up and down respectively by rotation. The threaded lifting outer tube and the lifting square tube can be raised and lowered separately by a single lifting rod, thereby realizing two-stage adjustment of the height of the micro-meteorological instrument and expanding the height adjustment range. The threaded lifting outer tube and the threaded sleeve are threaded together to achieve the first stage of lifting.

This allows operators to flexibly adjust the height of the micro meteorological instrument according to the needs of the site. For example, the height can be lowered in areas with low vegetation, and raised near trees or obstacles to obtain more accurate wind speed data, ensuring that the micro meteorological instrument is always at the optimal measurement height and providing high-quality meteorological data for wind power forecasting.

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.

[0033] Example 1

[0034] like Figures 1 to 11As shown, a monitoring device for wind power prediction includes a micro meteorological instrument 4 integrating a wind speed sensor, a wind direction sensor, a temperature sensor, a barometric pressure sensor, and a humidity sensor. Below the micro meteorological instrument 4 are a combined frame assembly 1, a fixed support assembly 2, and a lifting and adjusting assembly 3. The micro meteorological instrument 4 is fixedly mounted on the lifting and adjusting assembly 3. The micro meteorological instrument 4 can simultaneously collect key meteorological parameters such as wind speed, wind direction, temperature, barometric pressure, and humidity, providing comprehensive and high-precision data for wind power prediction. This avoids the problems of complex installation and asynchronous data from multiple independent sensors. The frame assembly 1 below the micro meteorological instrument 4 serves as the foundation. The support platform provides a mounting base for other components; the fixed support assembly 2 is responsible for firmly fixing the equipment to the ground, ensuring the stability of the equipment in harsh environments such as strong winds, and preventing it from tipping over or shifting; the lifting and adjusting assembly 3 enables the micro meteorological instrument 4 to be flexibly adjusted in the vertical direction to adapt to the influence of different terrains, vegetation or obstacles on the wind measurement height, so that the sensor is always in the optimal measurement position, thereby obtaining more representative meteorological data. It should be noted that the micro meteorological instrument 4 can be the micro meteorological instrument involved in the monitoring device for wind power prediction disclosed in the announcement number CN217422711U.

[0035] The fixed support assembly 2 includes a drive unit, a vertical insertion rod 28, and multiple diagonal bracing units. The vertical insertion rod 28 is connected directly below the synchronous drive unit, and the multiple diagonal bracing units are connected to the sides of the drive unit. The diagonal bracing units are located at the center of the four sides of the frame assembly 1. The vertical insertion rod 28 and the multiple diagonal bracing units are driven synchronously by the drive unit, enabling the monitoring equipment to be quickly and stably fixed to the ground. The vertical insertion rod 28 is inserted vertically into the ground and mainly bears the vertical tensile and compressive loads, providing pull-out and compressive resistance. Capabilities; Multiple diagonal bracing units are distributed in the middle of the four sides of the frame assembly 1, inserted into the ground at an angle, providing lateral support from four directions, enhancing the equipment's wind resistance and overall anti-overturning stability; The drive unit enables all the insert rods to move synchronously, avoiding the tedious installation one by one, greatly improving on-site installation efficiency, saving manpower and time costs, and forming a multi-point support structure that allows the equipment to remain vertical and stable on uneven ground, adapting to complex terrain, effectively resisting horizontal wind force and vertical load, and ensuring that the micro weather instrument 4 can still work reliably in severe weather;

[0036] The lifting adjustment assembly 3 includes a threaded lifting outer tube 31, a threaded sleeve 32, a lifting square tube 33, and a lifting rod 34. The micro meteorological instrument 4 is fixed to the top of the lifting square tube 33. The threaded lifting outer tube 31 is threadedly connected to the threaded sleeve 32. The lifting square tube 33 is movably inserted into the threaded lifting outer tube 31. Part of the lifting rod 34 is threadedly connected to the lifting square tube 33, and the rod of the lifting rod 34 passes through the bottom end face of the threaded lifting outer tube 31. The lifting rod 34 drives the threaded lifting outer tube 31 and the lifting square tube 33 to move up and down respectively by rotation. The lifting outer tube 31 and the lifting square tube 33 can be raised and lowered separately by a single lifting rod 34, thereby realizing two-stage adjustment of the height of the micro meteorological instrument 4 and expanding the height range. The height adjustment range is achieved by threaded engagement between the threaded lifting outer tube 31 and the threaded sleeve 32 to realize the first stage of lifting; the lifting square tube 33 is movably inserted into the threaded lifting outer tube 31 and threadedly connected to the lifting rotating rod 34 to realize the second stage of lifting; by rotating the lifting rotating rod 34, the lifting square tube 33 can be driven to move up and down relative to the threaded lifting outer tube 31, and the threaded lifting outer tube 31 can also be driven to rotate and lift relative to the threaded sleeve 32; this allows the operator to flexibly adjust the height of the micro meteorological instrument 4 according to the needs of the site, for example, the height can be lowered in low vegetation areas, and raised near trees or obstacles to obtain more accurate wind speed data, ensuring that the micro meteorological instrument 4 is always at the optimal measurement height, providing high-quality meteorological data for wind power forecasting.

[0037] Example 2

[0038] Improvements based on Example 1:

[0039] like Figure 1 As shown, the frame assembly 1 includes a base 11, a support pole 12, a top plate 13, side baffles 14, and universal casters 15. The universal casters 15 are located at the four bottom corners of the base 11. The top plate 13 is positioned parallel to the base 11 above it, and the two ends of the support pole 12 are connected to the top plate 13 and the four corners of the base 11, respectively. The side baffles 14 are fixed to the bottom surface of the base 11 and surround the universal casters 15. The universal casters 15 are located at the four bottom corners of the base 11, enabling the equipment to move and allowing for easy adjustment of its position or transfer to different measuring points on-site, thus improving the flexibility of use, especially suitable for wind farms that require multi-point monitoring. The side baffles 14 are fixed to the bottom surface of the base 11 and surround the universal casters 15, providing protection and preventing weeds, stones, and other debris from getting tangled in the casters. This allows the monitoring equipment to be quickly deployed to different locations and adapt to complex field environments, providing a flexible data acquisition platform for wind power prediction.

[0040] like Figures 1 to 6As shown, the drive unit of the fixed support assembly 2 includes a housing 21 and a positioning rotating rod 23, a drive gear 27, and multiple driven bevel gears 211 disposed within the housing 21. The housing 21 is fixedly connected to the top surface of the base 11. The positioning rotating rod 23 is vertically inserted through the top surface of the housing 21. A mating bearing seat 215 is connected between the bottom end of the positioning rotating rod 23 and the base 11. The drive gear 27 is fixedly sleeved on the rod body of the positioning rotating rod 23. The driven bevel gears 211 are arranged one-to-one with the inclined support units, and multiple driven bevel gears 211 are meshed with the drive gear 27. When the positioning rotating rod 23 is rotated, the drive gear 27 drives all the driven bevel gears 211 to rotate synchronously, thereby driving each inclined support unit to move. This ensures that the four inclined support units and the vertical insertion rod 28 are inserted or pulled out of the ground simultaneously, avoiding equipment tilting or insecure fixing due to inconsistent movements. In addition, multi-point synchronous drive can be achieved through one positioning rotating rod 23, improving installation efficiency and meeting the requirements of rapid deployment at wind power sites.

[0041] Furthermore, the diagonal bracing unit includes a diagonal bracing outer tube 22, a diagonal bracing insert rod 24, and a drive rod 29. The diagonal bracing outer tube 22 is uniformly fixed to the outer circumferential wall of the outer shell 21 in an outwardly inclined manner, and the tube body of the diagonal bracing outer tube 22 also penetrates the base 11 in an outwardly inclined manner. Part of the rod body of the diagonal bracing insert rod 24 is movably inserted into the diagonal bracing outer tube 22, and the pointed rod head of the diagonal bracing insert rod 24 is located outside the bottom end of the diagonal bracing outer tube 22. The rod body of the drive rod 29 penetrates the upper end of the diagonal bracing outer tube 22, and the rod body of the drive rod 29 located inside the diagonal bracing outer tube 22 is threaded into the diagonal bracing insert rod 24. A positioning seat 210 is movably sleeved on one end of the drive rod 29 located outside the diagonal bracing outer tube 22. The positioning seat 210 is fixedly connected to the top wall of the outer shell 21. A driven bevel gear 211 is fixedly sleeved on the rod body of the drive rod 29 located outside the diagonal bracing outer tube 22. The outer tube 22 of the diagonal brace is fixed to the outer shell 21 and passes through the base 11, providing guidance and support for the diagonal brace rod 24. This ensures that the rod is inserted into the ground at a predetermined angle, thereby forming the optimal support angle and effectively resisting lateral wind force. When the drive rod 29 rotates, the diagonal brace rod 24 moves axially along the outer tube 22 through threaded transmission, realizing insertion or extraction from the ground. The positioning seat 210 ensures the stable rotation of the drive rod 29 and transmits the axial force of the drive rod 29 to the outer shell 21. The driven bevel gear 211 meshes with the drive gear 27, allowing the rod to be inserted into harder soil with a smaller operating force. The four diagonal brace units are evenly distributed, providing diagonal support from four directions. Together with the vertical rod 28, they form a stable support system, improving the equipment's wind resistance and overturning resistance.

[0042] Furthermore, a limiting sleeve 25 is movably fitted onto the body of the positioning rotating rod 23, and the limiting sleeve 25 is fixedly connected to the outer shell 21. A support locking bolt 214 is threaded through one side of the limiting sleeve 25. A horizontally positioned rotating handle 26 is fixedly connected to the top of the positioning rotating rod 23 above the outer shell 21. The support locking bolt 214 is threaded through the side wall of the limiting sleeve 25. When the support locking bolt 214 is tightened, its end abuts against the positioning rotating rod 23, which can lock the positioning rotating rod 23 in its current position, preventing it from being stopped due to vibration or external force. The positioning rod 23 rotates unexpectedly, thus ensuring that the diagonal bracing unit and the vertical insertion rod 28 remain fixed. The rotating handle 26 allows the operator to apply force to rotate it. By rotating the handle 26, the positioning rod 23 is driven to rotate, thereby driving all diagonal bracing units to move synchronously and achieve rapid fixation. After fixation, tightening the support locking bolt 214 will lock it and prevent loosening. At the same time, the cooperation between the limit sleeve 25 and the support locking bolt 214 allows the operator to loosen the bolt first and then operate the handle when the fixed position needs to be adjusted, and then tighten it again after adjustment, making the operation flexible and convenient.

[0043] Furthermore, the vertical insertion rod 28 extends vertically through the base 11. A portion of the vertical insertion rod 28 is threaded into the positioning rotating rod 23. A limiting groove 213 is provided on the vertical insertion rod 28. A limiting slider 212 is fixedly connected to the hole in the base 11 through the vertical insertion rod 28, and the limiting slider 212 is engaged within the limiting groove 213. When the positioning rotating rod 23 rotates, the vertical insertion rod 28 moves up and down via threaded transmission, allowing it to be inserted into or removed from the ground. 213 and the limiting slider 212 form a sliding pair, which not only ensures that the vertical insertion rod 28 can only move along the axis and cannot rotate, but also plays a guiding role, ensuring that the vertical insertion rod 28 always remains vertical, making it less likely to loosen after insertion, thus enhancing the reliability of the fixation. The vertical insertion rod 28 and the four diagonal bracing rods 24 work together to form a three-dimensional fixation system with the center vertical and the surrounding diagonal bracing, which can effectively resist wind and vibration from all directions and ensure the stability of the micro weather instrument 4.

[0044] like Figure 1 , Figure 2 , Figures 7 to 11 As shown, a positioning bearing 39 is connected between the bottom end of the lifting rod 34 and the threaded lifting outer tube 31. The part of the lifting rod 34 located inside the threaded lifting outer tube 31 is threaded into the lifting square tube 33. The lifting rod 34 can rotate freely relative to the threaded lifting outer tube 31, while being constrained axially to ensure that no axial movement occurs during rotation. When the lifting rod 34 is rotated, the lifting square tube 33 is restricted from rotating because of its square cross-section and its fit with the square hole of the threaded lifting outer tube 31, ensuring that the lifting square tube 33 can only move axially to achieve the second stage of lifting.

[0045] The threaded sleeve 32 penetrates the middle part of the top plate 13 and is fixedly connected to the top plate 13. One side of the threaded sleeve 32 is threaded with an outer tube locking bolt 38. The threaded sleeve 32 provides guidance for the lifting and lowering of the threaded lifting outer tube 31. When the outer tube locking bolt 38 is tightened, its end abuts against the threaded lifting outer tube 31, which can lock the threaded lifting outer tube 31 at the required height and prevent it from sliding down due to gravity or external force. When the first-stage lifting adjustment is required, the outer tube locking bolt 38 is loosened first. At this time, the lifting rod 34 and the threaded lifting outer tube 31 are locked. Then, the lifting rod 34 is rotated to drive the threaded lifting outer tube 31 to rotate and lift. After reaching the position, the outer tube locking bolt 38 is tightened, thus realizing independent control of the two-stage adjustment.

[0046] Furthermore, a positioning sleeve 36 is movably sleeved on the lifting rod 34 located outside the threaded lifting outer tube 31. The positioning sleeve 36 is fixedly connected to the bottom end of the threaded lifting outer tube 31, and a rod locking bolt 37 is threaded through one side of the positioning sleeve 36. A horizontally positioned lifting handle 35 is fixedly connected to the bottom end of the lifting rod 34 located outside the threaded lifting outer tube 31. When the rod locking bolt 37 is tightened, its end abuts against the lifting rod 34, which can fix the lifting rod 34 and the threaded lifting outer tube 31 relative to each other, preventing them from rotating relative to each other. Combined with the outer tube locking bolt 38, independent two-stage lifting is achieved. Operation: When adjusting the first-stage threaded lifting outer tube 31, first loosen the outer tube locking bolt 38 and tighten the rotating rod locking bolt 37 to lock the lifting rotating rod 34 and the threaded lifting outer tube 31 together. At this time, turning the lifting handle 35 will drive the threaded lifting outer tube 31 to rotate and rise. When adjusting the second-stage lifting square tube 33, first tighten the outer tube locking bolt 38 to fix the threaded lifting outer tube 31, and then loosen the rotating rod locking bolt 37. At this time, turning the lifting handle 35 will only drive the lifting rotating rod 34 to rotate, thereby driving the lifting square tube 33 to rise and fall. The two-stage adjustment is integrated into one handle, which greatly improves the convenience of use.

[0047] Working principle: In the initial state, the equipment is moved to the designated monitoring point in the wind farm by means of the universal rollers 15 set at the four corners of the bottom of the base 11. After reaching the predetermined position, the operator first stabilizes the equipment on the ground by fixing the support assembly 2: rotating the rotating handle 26 located above the outer shell 21 drives the positioning rod 23 to rotate, and then through the meshing transmission of the drive gear 27 and multiple driven bevel gears 211, all drive rods 29 rotate synchronously; the drive bracing rod 24 extends outward and downward along the bracing outer tube 22, and its pointed rod head penetrates the ground to provide lateral support; at the same time, the rotation of the positioning rod 23 forces the vertical rod 28 to move downward in the vertical direction and insert vertically into the ground to provide pull-out and compression resistance. After being inserted into place, the support locking bolt 214 on the limiting sleeve 25 can be tightened to abut the positioning rod 23.

[0048] After the equipment is fixed, the height of the micro meteorological instrument 4 needs to be adjusted according to the site terrain and measurement requirements. The lifting adjustment component 3 provides two-stage lifting functions: when a large adjustment is required, first tighten the rotating rod locking bolt 37 on the positioning sleeve 36 to fix the lifting rotating rod 34 relative to the threaded lifting outer tube 31, then loosen the outer tube locking bolt 38 on the threaded sleeve 32, and then turn the lifting handle 35 to drive the lifting rotating rod 34 to rotate. Since the lifting rotating rod 34 and the threaded lifting outer tube 31 are locked together, the rotation of the lifting rotating rod 34 will drive the threaded lifting outer tube 31 to rotate together, so that the threaded lifting outer tube 31, together with the lifting square tube 33 and the micro meteorological instrument 4, rises or falls together to achieve the first stage of lifting adjustment; after adjusting to the appropriate height, tighten the outer tube locking bolt 38 to lock the threaded lifting outer tube 31 on the threaded sleeve 32. When fine-tuning the height is required, keep the outer tube locking bolt 38 in the locked state to fix the threaded lifting outer tube 31, loosen the rotating rod locking bolt 37 to allow the lifting rotating rod 34 to rotate freely. At this time, turning the lifting handle 35 only drives the lifting rotating rod 34 to rotate, driving the lifting square tube 33 to move up and down inside the threaded lifting outer tube 31, thereby realizing the second-level fine lifting adjustment. After the adjustment is in place, tighten the rotating rod locking bolt 37 again to lock the lifting rotating rod 34 and prevent the lifting square tube 33 from sliding.

[0049] Finally, the various sensors built into the micro-weather instrument 4 begin to work in real time. The wind speed sensor, wind direction sensor, temperature sensor, air pressure sensor and humidity sensor simultaneously collect on-site meteorological data, thereby enabling the prediction of wind power.
